Blown radiator fan fuse
Its been a while since I posted, busy year with new job, move to Ohio, etc.
What brings me here is that when working on my 93 SSE, I noticed the radiator fans weren't coming on. I found the big 40 amp MAXIFUSE blown. I replaced it and it blew again.
I did a search on fan problems here, but the posts I found didn't deal with blown fuses but the fans not turning on when they should, usually low speed.
Could someone please verify that I'm correct in these things I read from my searches:
- Both fans spin together, either high or low speed
- Both fans spin at high speed when the A/C is turned on - does this include the defroster?? Use it alot in the winter.
- Thermistor on LH side tells pcm when to go to high speed. Should read 4.4K ohms at room temperature
- Fan motor should read 15-20 ohms
I did notice that the LH side fan was winding down, but the RH fan was not when I blew the second fuse. This will be the first place I look tomorrow when I work on her. Any insight as to where I might find the short would be greatly appreciated.
Thanks in advance and Happy New Year to all.
